lThis invention has vto'dowith cabinets, such as areusedin commercial housesfor recelving and holding ice cream containers 'and the likefand 'ithas to do more particularly 5 with suchA cabinets which are' cooledfby Va power refrigerating apparatus. 4

Manufacturers of such vcabinets have'been confrontedwith.` a serious probleml in meeting the demandsof the market lasto the size and capacity ofthe cabinets. Commercial houses having an extensive business require very large cabinets, the smaller houses must have smaller cabinets, andthem'any intermediate sizes kof commercial houses require as many sizes in cabinets. Thisfresultsin confusion inthe manufacture :of the cabinets and prevents thejuse of standardized methods and apparatus.' and-accordingly the'c'ost of thecabinets is high; l l Y p The' present invention aimsfto providel a cabinet which. is composed' of anumber of units so as' to overcome these diiiculties.v 'Accordingly', theinventi'on contemplates a pri# mary unit which would be vthe minimum 'size required", and other'se'condary units which may be connectedf'to the' primary unit. The primaryunit is preferably equipped with part of a `-power refrigeratingapparatus,and arranged to be cooled by such apparatus, whereasl Athe"'secondary units are equipped only with a piping system nbut which is arranged so'that itcanbe connectedto the primary unit in such awayithat its piping Asystem becomes a part of the refrigerating' apj paratus. lThe secondary units can be used in any number desired, kand in 'thismanner any lsize or'capacity of cabinet can ybe obtained.T

Referring particularly to' Fig.l l, the ,prif maryy unit is shownzas .consisting-'of a cabinet for holding asingle ice cream container; yThe cabinet isi!constructed,preferably,of` an out? side shell 'i1 of wood," and "an -zinterrnediate layer 2' of insulating material, .such. ascorlr, and an inner structure 3 of moulded stone. Y This moulded stone is preferably. anoXy-chloride cement which I have d isclosedina num;

I Embedded' in this cast stone is a coil l5 for the purpose of receivingthe refrigerant.

This primary unit is shown as connected by means of'conduits' and 7=to a refrigerating 86 mechanismf4 including alfniotor, Vcompressor and condenser..y The refrigeratmgr yrnecha- `nism shown is of the'iioodedtype wherea 'boiler is'u't'ilized in which the'liquid refriglerant boils. This boiler is referencedfflO, and 90 Ais preferably disposed within 'the primary `unit,"an'd leading from the boilerare pipel ,Y

mains-11 and l12. These pipemains -extend' across the unit and have their. ends capped, as shown fatlS.` The coil 5 is connected -lto 95 n the two-mains so .as to receive refrigerant therefrom. The .arrangement isA dagmvnbl 'matically `shown/in'Fig 8 ingyapparatus extractsthe heat 4from it's`"s'ur .1100

2 l andere roundings as well as the coil 5, I provide the primary unit with a passageway 14, and a passa eway which connect the ice cream container receiving part with a chamber 16 which holds the boiler. With this arrangement one side of the primary unit has ka divided wall structure with a layer of'insulatin material 17 enclosing the chamber 16. T isk provides for a circulation of air within the primary unit so that the Iheat absorbing qualities of the boiler 10.may be utilized. v

Referring now to Figs. 2 and 4, each 'primary unit will be seenfto include a moulded stone wall 20 having a coil 21 embedded therein. Each unitis-provided` with pipe f and to which each coil is connected. .These mains 22 vand 23 which .extend across the unit removed, and the moulded s'tone of a secondaryy unit placed against the moulded stone of the primaryunit. The section A of the wall structure may then be `disposed over the exposed side of the secondary unit. This is shown in dotted lines of Fig. 2.l c

In order that thepipe mains in the secondary unit may be connected to the pipe mains in the primary unit, thek walls o each unit are cut away, as shown inv Figs. 6 and 7. To connect the* units togetherthe caps 13 are removed andthe mains and the twov units are connected by means of pipe couplings 30. This structure leaves the pipe cou lin s and a portionof the mains'exposed. or t e purpostof covering these portions, in order to maintain the eiliciency of the cooling a` paratus, a block 31 isprovided. This b oc is of a size to fit nicely within the recess formed by the two cut away portions of the' units,

' and it is recessed as at 32 for the purpose of accommodating the .pipes and` unions. This block may be made up of a section of moulded stone, and an intermediate layer 'of cork, andan outside layer of wood, but of course,`it can be made up of ablock of` one ymaterial-.if such 11n-.arrangement is found expedient. The mains 22and 23 in the secondary unit are now closed by caps and the lcabinet'hasbeen enlarged by one unit. In supplying the primary unit to the trade,

the refrigerating'mechanism will be of sufficientvcapacity to handle the primary unit and a number of secondary units. The cabinet may be enlarged yby the addition of any desired number of secondary units. The cut away portions ofthe walls of the primary unit, and all of the secondary units are of the same size so that the blocks 31 may be of a given size, and are fitted in between two secondary units in the same manner as between the primary runit. and first secondary unit.

As indicated at 35 (Fi 4 the last, or end secondary unit,` is of su stantially one-half the size of any intermediate recess formed by two adjacent units. For the purpose of closing this recess a smaller block may be.' used, but this block will otherwise be constructed in accordance with the block shown in Fig. 7. For the purplose of convenient illustration the invention as beenshown and described as including a yprimary unit having but a single containing chamber.V This would be thesmallest primary unit, but of course if itr is found expedient, a primary unit having two or more containers could bemade. To this larger rimary unit as many secondary units could added as desired.

`The invention. has been described and shown in connectionl with a refrigerating apparatus ofthe flooded type wherein ,aqboiler and coils contain liquid refrigerant which boils and absorbs heat. However, the invention is egually well adapted for use with other typeso `refrigerating apparatus, as for instance, the type where a limited amount ofy liquid refrigerant enters the coils and expands to a gaseous state therein.v It will be understood that intheuse of ice cream cabinets of this character parts of the refri erating mechanism such as the motor, condgenser and the like, are located at a remotepoint, as for instance, in the basement, and the Aconduits 6 and 7 connect the same with the cabinet-vwhich'is located in a place which ishandy forthe purpose. f l Y' The invention is beneficial for the manufacture of such devices and for the purchaser and user. ,The rimary unit and secondary units can be ma e under standardized manufacturing conditions `with the use of standardized vmethods and apparatus.v The purchaser is enabled to specify vand obtain a cabinet of any particular size, and yet'the cost to himwill notbe increasedby reason of his particular spccifications since themanufacturer is ena led to produce the cabinet in vstandardized units. Moreover, when a user of such a cabinet finds it necessary to have a larger one, as for instanceA by reason of increase of business, it is onlynecessaryto purchase one or two secondary units and connect them to his'present-equipment. y
